6. Natural Frequency of a Bowl-Type Vibratory Feeder 6.1 Fixed type vibratory feeder. In this type, the base of the feeder is attached to a foundation without a vibration isolator as shown in Fig. 1(d), so the vibratory system can have one-degree of freedom. The natural frequency of this type is expressed by 0 30 60 90 INCLINATION OF SPRING deg
